I used my 99 2500 today for the first time in 8 weeks. The truck sits in the driveway exposed to all kinds of weather, which lately has been a lot of rain. The drivers side carpet was saturated with water. I spent the afternoon removing the seats and console so that I could remove my soggy carpet. The majority of the water was around the drivers feet area, there was no water in the back area under the sliding rear window so I think the leak could be near the cowl area. Is there a drain around the cowl that could be plugged causing water to enter the cab? The door seal seems tight and the window was completly closed. I am open for any advise. Thanks , Charlie.
